A scheduler that knows you.
FSRS-6 spaced repetition brings each word back exactly when you need it. In Advanced Mode, it tunes itself to your memory patterns.
Fewer reviews. Stronger recall.
Native iOS · built for adults
Build a language with a method that actually sticks.
Tongueforge is a spaced-repetition app for people learning properly: typed recall, reading passages, scripted conversations, listening practice, and a smart scheduler that knows exactly when you need to see each word again. No game-layer noise, no guilt.
How it differs
Serious tool, not streak theater.
Tongueforge is designed for adult learners reactivating dormant skills or building real production ability, not casual tap-through practice.
Typical gamified apps
Easy interaction, easy forgetting.
Recognition-heavy: multiple choice and swipe gestures let weak memories slide by.
Streak pressure: the routine becomes the product, and missing a day feels like failure.
Thin context: isolated words rarely prepare you to speak or parse the real language.
Tongueforge
Harder work, better results.
Typed answers: you retrieve the word, tense, or phrase instead of spotting it.
Real language, not just cards: curated reading passages, scripted conversations, graded reader stories, and listening practice woven into your day.
Feedback that teaches: miss an accent and the app says "Almost, check the accents." Then you type the correct form once—because that's the teaching moment.
Progress that lasts: real milestones. Words made solid, level reached, the day you came back. No streaks to protect, nothing that expires.
Why adults choose it
Three reasons it feels different immediately.
Content with real range.
Vocabulary, conjugation, grammar, reading, dialogues, and stories—curated per language, gated to your level, A0 to C1.
Start where you are, never drown in the wrong material.Native, private, and fast.
Built with SwiftUI, local-first with private iCloud sync, home-screen widgets, and no ads or third-party tracking.
Your learning data stays yours, even offline.
Inside the app
Built to be used every day.
The daily loop, end to end: see what's ready, review by typing and getting corrected, and read progress that actually means something.
Today. What's ready, at a glance
Review. Type it, get corrected
Progress. Honest, readable signal
Science teaser
Desirable difficulty is the point.
Bjork's idea is simple: if practice feels too easy, it usually is. Tongueforge gives you better timing, harder recall, real context, and tutor-like correction. Delivered with warmth, never guilt.
